courieR

Migrate R packages between R versions — no reinstalling.

courieR detects every R installation on your machine and syncs packages between them — from the console or a point-and-click dashboard.

Install 

install.packages("courieR")
library(courieR)

hub()                      # open the dashboard
migrate("4.5", "4.6")     # one-liner CLI migration

Dashboard

Select a source and target R installation, click Compare to see what’s missing or outdated, then click Ship. Progress streams live in the log pane — no frozen screens.

Bulk Dispatch: select source/target, compare, ship
Bulk Dispatch: select source/target, compare, ship

How it works

🔍 Auto-detect Finds R installs from the registry, Homebrew, rig, conda — no paths to configure
📦 pak-powered Resolves CRAN, GitHub, and Bioconductor packages from source metadata
🖥 Dashboard + CLI hub() for point-and-click, ship() for scripting — same engine

Works on Windows · macOS · Linux. No packages required on the source R installation.
